I compiled the latest mkfs.jffs2 and run it as
mkfs.jffs2 -l -e 128KiB -d /opt/src/romfs -o /opt/src/images/root.jffs
and load the image at 0x000240000 on my intel 28F640 J3 A (8Meg strata flash)
the image I make has lots of Magic bitmasks in it, just not at the offsets
jffs2_scan_eraseblock is looking for.

Which is right, mkfs.jffs2 or linux? or do I not know how to use mkfs.jffs2?
